Metrious the Soulbinder
Level 3 | DARK | Spellcaster | Effect

1000 ATK / 2500 DEF

Card effects that deal damage to a player now increase their life points for that amount. This card banishes itself after 4 turns, dealing damage to players equal to the amount that life points that players gained while this card was on the field.

Any effect that would inflict damage instead makes either player gain that much LP, instead. During the 4th turn after this card was Summoned: Banish this card, then both players take damage equal to the LP they gained while this card was face-up on the field.

 

----

Several things to note:

• Card is basically Prime Material Dragon that burns after four turns.
• Stats are too high for a Level 3; talking about its DEF (lower it to 1500 or something). ATK is fine.
• LP gain is rare, outside D/D's using d'Arc to recover LP from Contracts. In other words, amount of Decks this counters or works with are rare (in terms of real gameplay).

I might want to mention that the reason I choose the high stats (for a level 3) is so that it serves as a scapegoat and force the oponent to get rid of it as soon as he/she benefited from the card. I also though of a combo were to would "heal" the opponent through this effect, deal some battle damage to them with a OTK/Control style deck (Think of a Malefic monster or a Gravity Bind play) , then this card would deal its damage from its effect after the fourth turn leading to a OTK.

4 turns total = 2 of your own turns. The fact Call of the Haunted and other effects can put it onto the field during your opponent's turn means this is actually.... a quick effect?

It is using the ways of Perfectly Ultimate Great Moth, but that card has no way of making the X turn it needs end up on your opponent's turn, making its old form of lore not really that big of a deal.

 

I think the OP needs to contain the flavor or the reason in general as to why 4 turns is needed. I think the effect would be better off as a Spell Speed 1 effect that you can just trigger at any of your Main Phases. 

 

This card is essentially Jigen Bakudan but a little bit faster and with a little bit more of a body, but unable to really do it on its own after that amount of time....

I think it should not take extra turns and should just stick to whatever it builds up within that turn it decides to blow up, and that its blow up end result is burning the opponent and healing you by that amount, while the build-up is simply cancelling the damage you take. It'd provide a tiny bit of an advantage to Ring of Destruction but not much else.

 

Rather than the odd 2500 DEF, I think it instead could use built-in protection. Something like "if this card would be destroyed, it loses 500 DEF instead" and have it have around 1500 DEF like that (you can always increase it with other effects so it sounds alright)
